Many studies have addressed a psychiatric analysis of self-injury patients who have self-injurious behavior and who have attempted suicide. Few studies on the injury characteristics of self-injury related trauma patients have been conducted. We analyzed the injury characteristics of self-injury patients.
A retrospective review of the medical records extracted from the injury surveillance system of Wonju Christian Hospital for the period from August 2006 to February 2008 was conducted. Of the 121 cases extracted, 103 were included in this study. We analyzed the sex ratio, age group, place of injury, injury mechanism, location of injury, management results, injury severity, and relation with drinking.
One hundred three cases were included (sex ratio: 1.06), and the mean age was 33.9+/-14.2 years old. Fifty-six patients (54.4%) were discharged from the emergency department (ED) on the day of injury after primary care, and 9 patients (8.7%) were discharged, because they refused treatment. Seven patients (6.8%) died. Of these, 4 patients (3.9%) died after attempted cardio-pulmonary resuscitation in the ED, 1 patient (1%) was dead on arrival, and 2 patients (1.9%) died after admission. Sixteen patients (15.5%) were admitted to the hospital, including 2 patients (1.9%) needing emergency surgery. Sixteen patients (15.5%) were transferred to other hospitals. Sixty-one cases (59.2%) involved drinking, and 31 (30.1%) did not; for 11 cases (10.7%), the involvement of drinking was unknown. The mean revised trauma score (RTS) was 11.26+/-2.52, and 88 cases (85.4%) hat a RTS of 12. The mean injury severity score (ISS) was 5.80+/-14.56, and 9 (8.7%) severely injured patients had scores of more than 15.
Most self-injuries were mild traumas related to drinking and occurred at a young age. Most cases were not so severe, and the patients were discharged from the ED, but some patients needed hospitalization. Other patients had injuries so severe that they died.
